Constant phase element
open-in-new
<p>In <a href="/facts/Electronics/E4JhgISq">electronics</a>, a constant phase element is an <a href="/facts/Equivalent_electrical_circuit/IxE5vpGR">equivalent electrical circuit</a> component that models the behaviour of a <a href="/facts/Double_layer_(electrode)/QhTTkyVs">double layer</a>, that is, an imperfect <a href="/facts/Capacitor/hyowqv7n">capacitor</a> (see <a href="/facts/Double-layer_capacitance/j4QhohBG">double-layer capacitance</a>). </p><p>Constant phase elements are also used in equivalent circuit modeling and data fitting of <a href="/facts/Electrochemical_impedance_spectroscopy/BYQ9lQu0">electrochemical impedance spectroscopy</a> data. </p><p>A constant phase element also currently appears in modeling the imperfect <a href="/facts/Dielectric/PnVt9P2G">dielectrics</a>' behavior. The generalization in the fields of imperfect <a href="/facts/Electrical_resistance/hxSt0UAj">electrical resistances</a>, <a href="/facts/Capacitance/0pH046TL">capacitances</a>, and <a href="/facts/Inductance/oIxj7JxX">inductances</a> leads to the general "phasance" concept: <a href="https://fr.scribd.com/doc/71923015/The-Phasance-Concept">http://fr.scribd.com/doc/71923015/The-Phasance-Concept</a> </p>
